I have been obsessing ( a bit ) 
…about how to handle the Balanced output from my Lumin T3. I have used the App to choose low analogue output on the Lumin …I use the output volume fixed. …and cannot be sure from reading the spec sheet what the actual fixed output is in V from the T3. Can you tell me what the output is when set to Low and using fixed volume out please ?
My Pre Amp is a Yamaha C5000…do you mind checking the specs of it online. To me it appears that it will overload at 2.8 V…in which case I may need to Attenuate the input on the Yamaha by engaging the -6db switch on the input…thus allowing an input level from the T3 of 5.6 V…please advise…thanks in advance.
X1 / P1 / T3 / T2:
Analog Output Level Normal: 6V rms XLR balanced
Analog Output Level Low: 2V rms XLR balanced
I suggest setting it to bypass.
In case it still sounds too loud to you with Analog Output Level Low, reduce Lumin Max Volume %.
Thanks for help . I really appreciate 
it.
